PCI, S3 Virge DX/GX 375/385 chipsetVery difficult to install. First I put the S3 Virge card in my system alone and plugged my large Gateway monitor into it-- that made Windows shut down!!(I think that monitor may be incompatible with the Virge card.) Then I started again. I put in the Rage Fury Pro and attached the Gateway monitor to it, and put in the Virge card and attached monitor #2 to it. That worked fine. Then I put in the 3DLabs graphics card and attached monitor #3 to it. Eureka! It works! 3 monitors on a budget. All 3 graphics cards are using the WinXP built-in drivers.
